PermMapper is a coal reservoir permeability measurement service that provides a means for determining bulk permeability from monitoring and analysis of pressure transients induced in the reservoir. Pressure transient analysis (PTA) techniques also yield values of average reservoir pressure, radius of investigation, total skin, conductivity and half-length of hydraulically induced fractures, depending on the type of test employed to induce the pressure transient. The service uses industry leading open hole permeability test tools, and real time downhole pressure measurements.
